Element X can donate 4 electrons, X would most likely belong to the same group in the periodic table as that of
Si
Given that, the element X can donate 4 electrons. Hence, it has valency 4. Hence it is likely to be in group 14 of the periodic table, adding 10 to 4 (valency), we get 14, which is the group number. In the given options, silicon (Si) is a group 14 member.
